Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a heating bread machine equipped with an automatic bread maker that automatically performs everything from kneading the ingredients to fermentation and baking once the specified ingredients are put into a kneading container and set. It is related to cooking utensils.

BACKGROUND OF THE INVENTION As is well known in the art, the bread manufacturing process begins with kneading the ingredients, followed by subsequent fermentation, degassing, molding fermentation, and baking.

Currently, there are fully automatic bread machines that perform these bread-making processes automatically, and semi-automatic machines that perform the primary fermentation, take out the bread, manually degas it, shape it, and bake it. Various methods have also been used. The process of kneading the bread ingredients involves rotating blades installed at the bottom of the kneading container at approximately 300 revolutions per minute, and also rotating in the forward and reverse directions. Approximately L5K as above
Since the kneading is done with a fairly strong force of about 300 rotations at the torque of the g/prep, it is necessary to securely fix the kneading container with strong force.

FIG. 4 shows an example of a conventional method for fixing a kneading container. Reference numeral 1 denotes a container for storing materials, and 2 is a foot portion for attaching the container 1 to an engagement receiving portion 3 provided at the bottom of the heating chamber. The foot portion 2 is provided with several protrusions 4 as engagement portions, and by placing the container 1 on the bottom of the heating chamber and rotating it, the protrusion 4 of the foot portion 2 and the engagement receiving portion 5 on the bottom of the heating chamber are connected. are engaged and fixed. Reference numeral 6 has a circular foot portion 2 and a locking mechanism to prevent the container 1 from coming off due to rotation, and is configured to be attached and detached by moving a lever 7 up and down.

Problems to be Solved by the Invention With this method of rotating and fixing the kneading container, both hands are required to attach and detach the kneading container. It was difficult to remove the container while it was still hot. In addition, for electric open and open microwave ovens equipped with a bread-making function, space is limited as they are built into a box-shaped heating chamber, so the side door must be opened and the kneaded diluted ingredients must be inserted into the heating chamber. It was quite inconvenient to use, as it had to be installed at the bottom of the heating chamber by being dropped from above and then rotated. Further, in the case of a warehouse interior that has been painted or surface treated, there is a problem in that the friction at the time of engagement damages the coating or surface treatment, making it undesirable in terms of appearance.

Furthermore, the engagement receiving part at the bottom of the heating chamber is made of sheet metal.
Since the edge of the sheet metal is exposed, it is difficult to clean and there is a risk of cutting one's hand when wiping off dirt, making it not only difficult to use but also unhygienic and dangerous.

In addition, with the rotation fixing method, when the kneading container is attached and detached, a large frictional force acts on the engagement part, the engagement protrusion and the engagement receiving part wear out, and the engagement force decreases as the kneading container is used. There were a number of problems, such as the inside of the device rattling or coming uncoupled.

The present invention solves these conventional problems, and replaces the frictional force caused by rotating the engaging portion with a simple engagement by a protrusion that does not apply frictional force and an attractive force by magnetic force. By making the rotation stopper square, the engaging part is simplified, making it easy to attach and detach, and easy to maintain.
Furthermore, the present invention provides a heating cooker that does not wobble due to wear. Furthermore, by providing a handle on the side of the container, the container can be easily attached and detached with one hand, thereby providing a heating cooker with excellent safety.

Means for Solving the Problems The heating cooker of the present invention has a kneading container and an engagement receiving part at the bottom of the heating chamber in a shape with square or more square corners, and a protrusion for locking and a heating part on the kneading container. This method attempts to solve the conventional problems by providing a hole punching part in the engagement receiving part in the chamber and providing a magnetic material on the partner of the kneading container and the engagement receiving part.

Function The heating cooker of the present invention has a rectangular engagement receiving portion between the kneading container and the bottom of the heating chamber, so that the force in the rotational direction is received at the corner portion, so that the strength in the rotational direction is increased and the kneading container is No rattling or disengagement. Also, because of the square shape, the position can be easily determined and the installation can be done easily.

Furthermore, by providing a hole punching part on the protrusion of the kneading container and the engagement receptacle in the heating chamber, and by providing a magnetic material on the partner of the kneading container and the engagement receptacle, the upper and lower parts of the protrusion and the engagement receptacle are fixed. Since it is fixed using the absorbing power of the magnet, there is no need to worry about abrasion of the engaging part, and there is no chance of damaging the paint or surface treatment.

Further, if a handle is provided on the side of the kneading container, it can be attached and detached with one hand, making it even more convenient to use, and also has the advantage of making it easier to take out the baked bread.
